Caging carbon dioxide: Self-assembled discrete palladium(II) [Pd2(L)4]4+ cages with 2,6-bis(pyridin-3-ylethynyl)pyridine) ligands (L) have cavities, which bind guests containing carbonyl groups through hydrogen bonding interactions. In the solid state these cages have now been shown to bind up to four CO2 molecules, with selectivity over N2. Long-range order in the packing of the molecules in powdered samples of the compound does not appear to be necessary for their activity, making their preparation easy. Additionally, the cages can be readily functionalized, opening up avenues for selective guest binding and gas separations. More information can be found in the Full Paper by B. F. Abrahams, J. D. Crowley et al. (DOI: 10.1002/chem.201701477).
